T1059.007 JavaScript
The PDF file contains an embedded URL that directs users to a suspicious domain, likely for phishing or malware distribution. ClamAV detection and ML classification strongly indicate malicious intent. The document body, though heavily obfuscated, appears to be a lure related to a 'study guide'.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://trafffe.ru/123?utm_term=texes+life+science+7-12+study+guide PDF link annotation
